NOXIOU FUMES WHEN EXPLCDING NITRO- GLYCERIN.

j Patented. Aug. 3, 1909.

Application filed September 14, 1908, Serial No. 453,048.

T 0 all whom it may concern:

Be it known that I, FRAxK P. BETTANIN, subject of the King of Italy,residing at Bessemer, in the county of Gogebic and State of Michigan,have invented certain new and useful Improvements in Compounds forEliminating Noxious l-umcs when EXPlUtling Nitroglycerin, .of wl1ich thefollowing is a specification.-

Nitro-glyeerin, as generally manufactured, gives off noxious gases andlarge quantities of smokev when exploded. extremely poisonous andinjurious to health and often prove fatal, particularly when generatedin close and confined places, such as mines, tunnels and the like, henceserious loss of time is occasioned to clear such places of the smoke andgases al'ter blasting, or necessitating thc'use oi expensiye ventilatingappliances. T

The purpose of the present invention is to supply a compound which mayeither be combined with the Intro-glycerin or explosive or employed inconjunction thcrewiti so as to be set off simultaneously with the ex iloThese gases are.

l l l l l l l sion of the nitro-glycorin so as to neutra izc oreliminate the noxious fumes and smoke, thereby obviating theobjectionable l'caturcs heretofore experienced at -'l herewithcnumerated. v

In preparing the compound for use with dynamite containing 60 per cent.of nitro glycerin as a basis, potassium chlorate approximately 18 percent. is employed, or in lieu thereof, a like amount of any otheroxidizing agent may be substituted; .6 per cent. oil of pine, tarorrosin is added to the potassium chlorate or oxidizing agent. 'lhcseingredients are thoroughly mixed and may be added to the ni-tro-g"cerinpowder or explosive or put up in capsule or other convenient form andplaced in contact with or close to the powder so as to be set oil withthe explosive. The great quantity of oxygen given oil' by the compoundat the instant oi' the explosion combines wit h the intense heat or lameand eliminates the noxious fumes and eil'ectually destroys the same.Whatever may be the operation, it has been found that by use of thecompound the noxious fumes and dense smoke given otl' by nitroglycerinpowder when exploded arc practically eliminated] Having thus describedthe invention, what is claimed as new is Ari-explosive compoundconsistingi'if dynamite, potassium chlorate and oil of pine combined inabout the proportions stated.
